Robbie Williams wrote 'Take the Crown' in eight days.

The 'Candy' singer worked with Australian dance duo the Undercolours on his latest album, and was surprised at how quickly it all came together.

In a video posted on his official YouTube channel, Robbie explains: ''My brother in law - who's in a rap combo called The Connects - his music got 40 per cent better overnight and I said, 'What's going on?'

''He said: 'We met these guys in a bar, these Australian guys, and they produce and write songs'. I said to him: 'Well, get them up to the house,' and within eight days, we'd written the album.''

He also said the pair had ''breathed youth'' into the music, adding: ''I found it to be a very fortuitous blend straight away. More so than anything I've ever done in the past really.''

Robbie is joined in the video by producer Jacknife Lee, who also worked on the album, and he explained how he got on board.

He said: ''I think any artist who is going to have longevity needs to try stuff. That's the bit of Rob that I'm attracted to - a fearlessness about being big, about connecting with people and he's one of those artists who it's very hard not to be a fan of.''
